IMPROVEMENT IN CORN-PLANTERS.

bpeeiieationy forming part of Letters Patent No. 28.6l5, dated June 5,1860.

To all whom may concern:

Be it known that I, PTOLLMAN STOVER, of Vest Alexandria, in the countyof Preble and State of Ohio, have invented a new and use-y fulImprovement in Corn-Planters; and l do hereby declare that the followingis a full and exact description of the same, reference being had to thedrawing and letters marked thereon, which form a part of thisspecification.

In the annexed drawings, Figure 1 is a plan view, Fig. 2 a view takenfrom the back, and Fig. 3 a vertical longitudinal section, of theoperating parts.

The frame of the machine, A, rests on-three rollers, two of them,- B,acting also as tractionrollers and pressing the soil on the seed afterit has been planted. The other, C, is placed on a rotating pivot, sothat it is capable of acting in some measure as a guide to the machine.Secured to the machine-framing there are also six shovels, D, plows, orimplements, two of them, c-one before each seed-tube-opening the ground,and four of t-hem, b-two to each seed-tube-acting as coverers, and atthe same time cultivating the. ground as the machine moves along.

On the side of one of the traction-wheels is secured a gear-wheel, E, ofa less diameterin fact, -sufciently small to be out of the way of anyobstruction it might meet with on the ground that would be likely toimpede its action; and gearing with this wheel is another that has itsjournals in the upright frame F. This latter wheel, G, can slide in itsjournals,

` and on one extremity of its shaft, under the drivers seat H, a crank,I, is placed. By means of the lever or handle J and spring c, thedriver, when sitting on his seat, can throw these two toothed wheels Eand G in and out of gear, as he desires, withoutmoving from his seat,and can retain them in either position by means of the spring c whilestill guiding the,

I on four posts, is the seed-box N, in which the seed-slides M work.These seed-slides are two 1n number-a lower one, f, and an upper one,

(/-both moving at thesame time, because both connected to the samepiece, L. The upper one,

g, is so formed as to act as a cut-.off valve, the

edge of the valve being beveled to carry any seed above it which may bein the way to hinder its motion, and to pass freely through the box fullof seed. The lower one, j', has an aperture, l1, in it, through whichthe seed can pass into the seed-tube O, that delivers the seed to theground. This aperture 7L is so placed relativelywith the cutoff, as seenin Fig. 3, that, although moving at the same time, the aperture 71v onlyopens communication between the measuring-space in the bottom of theseedboX and the seed-tube O when it (the measuring-space) is closedabove by the cut-off y. This measuring-space is formed by a groove inthe bottom of the box N, closed at one endthe front-by a square piece, jwhich is secured in its place `by a wedge, so that it can'be placed inany position-that is to say, farther in or ont-to make themeasuring-space larger. or smaller, to deliver more or less seed asrequired at each operation of the seed-slides. At the back is anotherrectangular-piece, k, which isv kept in its place by a spring, P, that,being secured tothe back of the seed-box, presses f against it, but hasat the same time elasticity enough to allow it'to yield if any kernel ofcorn should lodge and, but for this provision, tend to choke themeasuring-space and prevent the free action of the seed-slides; but whenthe seed or kernel of corn is freed and has dropped down the tube intothe ground,

motion by the toothed wheel E,.connected to` its side, to the toothedwheel G, and this, by means of the crank T on its shaft and the link,moves the seed-slides and so delivers the seed into the ground, where itis covered by the shares b, and the soil pressed down by thetraction-rollers B. The extremes of motion to which the crank, link, andseed-slides are subject and the position ofthe cut-off valve or slideand the delivering one at the different points of the stroke are shownby the red and black lines in Fig. 3. e

The peculiar advantage of thisv corn-planter is that a seed of corn orkernel cannot choke the measuring-space and from its hardness preventthe free action of the slides, and also tend to break the operatingparts; but provision being made for this contingency, there is no dangerof the machine becoming damaged, and thus causing not only expense andinconvenience, but also hindering the sowing process at the very timewhen it should be performed with dispatch. Moreover, the machine issimple, cheap, and eiiicient, and as all its parts are easy of access,should any portion become Worn or from accident broken, it can easilyand conveniently be replaced, and at the same time the wholemacl1ine,when in op- PTOLLMAN STOVER.
